Ta all wh m y mat I l Be it known that I, STEPHEN S rrrr,

ya itiz nof th United-States, residing at Boise, in the county of Ada and Stateof mechanism and more particularly to theat:

Idaho, have invented-certain anduseful Improvements in Block-Hooks,of which the following is a specification,

This anveutron relates to; black and tackle taching hook for snatch blocks and the like adapted to be used in connection with the flexible power transmitting means.

The present invention is a division of my co pending 118,571, filed September, 5, 1916.

One of the objects of the present invention is to provide a simple and practical attaching means or hook particularly adapted for use in connection with snatch blocks,

which will be reliable and eiiicient in use and 7 operation. A further object is to provide an improved hook and. guard therefor adapted to prevent accidental removal of the flexible power transmitting means or cable. attached to the hook.

Other objects will be in part obvious from the annexed drawings and in part indicated .in connection therewith by the following analysis of this invention.

This invention accordinglyconsists in the features of construction, combination of parts and in the-unique relations of the membersand in the relative proportioning and to with the guard in open position;

Fig. 2 is an enlarged perspective view of the hook in closedposition.

a Fig. 3. is a detail transverse sectional view of the hook. V

Referring now to the drawings in detail and more particularly to Fig. 1, 5 represents 7 a snatch block of any desired type having an attaching ring 6 at one end thereof and application Serial Numberi s p-i ate ra em r eee ns'tl W sldes'ofthe block atftheop'posite end. The

hook which ismcunt'ed in this cr'oss member 8 comprises a member .1'0curved at I one 1 t e- 3 1 h nd havi g j i pe ite ad. mislr a ar a-ar s ti n and Pa s n through a hole in the central part ofthe with this shank portion is a second member 11 also havlng asemlcircular cross section and the inner ends of both members 10 and 11 are flanged-over at the base-or inner Specification of Lettersr'atenti t v; 13, 191557; Dividedand .thisapp licaticnfiledjaiiiiaryi mem r clear y-s ow al s-1.2- Cease side of the member 8 to prevent removal thereof through the circular opening in the member 8. This peculiar construction and method of attaching permits both members to have independent relative longitudinal movement. The member 11 has its outer end 12bent sharplyat right angles and has pivotedthereto a latch 13 provided with an opening nearits outer end adapted to catch over an auxiliary hook 14 at the free'end of the member 1 r 7 When a rope or cable is attached to the hook it is preferable to open the latch 13 and pass the cable up into the crookof the hook 10. The latch is then snapped over the auxiliary hook. 14 and any-pull exertedon the rope will cause a .relative longitudinal movement of the hook 10 with respect to the latch and firmlyseat the latter in closed position. As long as this tension is exerted it is impossible to remove the latch.

It is thus seen that thepresent invention provides a simple and practical hook and lock therefor particularly adapted for'use in 5 connection with snatch blocks, although it is of course susceptible without material:

modification to ordinary blocks.

It is believed that the device is reliable and efficient in use and operation and is adapted to accomplish among others all of the objects and advantages herein set forth.

I realize that considerable variation is possible in the details of construction and arrangement of parts without departing from the spirit of myinvention, and Itherefore do not intend to limit myself to the specific form shown and described. a I

Having thus described my invention what I claim as new and desire tosecure by Let.-

ters Patent isc y 1'. In combination a transverse. member adapted to form the end of a block orv the like having a central opening, a hook hav- 7 mg a shank mounted in said opening and r S longitudinally movable therein, a second member having a shank arranged parallel to said first mentioned shank and together completely filling said opening, means for preventing removal of said members from the opening, a latch carried by said last mentioned shank adapted to co-act With the end of the hook whereby when strain is exerted on said hook said latch will occupy a locking position and act as a guard for a flexible member passing through said hook.

2. In combination with a transverse member adapted to form the end of a block or the like, and having a central opening, a hook having a shank passing through said opening and partially filling the same, a second member having a shank also passing through said opening, the shanks of both members being flanged over to prevent removal, said last mentioned member having a latch pivotally mounted at its outer end adapted to coact With the end of the hook and act as a guard for a flexible member passing through said hook.

In testimony whereof I affix my signature in presence of two Witnesses.
